Intended Use

This is a stationary digital x-ray system for general radiography and RSA (Roentgen Stereophotogrammetric Analysis procedures). Not for mammography.

Device Description

The Halifax SR Suite consists of two X-Ray imaging systems; the two systems are integrated through a synchronization switch. The switch allows the two X-Ray imaging systems to fire simultaneously, providing a pair of X-Ray images from different perspectives to be taken at the exact same time. This process allows for Roentgen Stereophotogrammetric Analysis (RSA). RSA is a stereo x-ray technique that enables measurements more precise than single plane radiography based on phantom precision studies. The resulting level of precision provides measurements of joint replacement stability.

The Halifax Imaging Kit is part of the SR Suite product line and provides an alternative path to creating an SR Suite. The Halifax Imaging Kit consists of FDA cleared and/or certified X-Ray components integrated into an existing digital radiography room already containing an FDA cleared x-ray imaging system to form an SR Suite. The exposures of the Halifax Imaging Kit and the existing Digital Radiography (DR) system are synchronized by replacing the trigger switches of the two systems with either the Universal Synchronization Switch or the Imaging Kit Control Module (IKCM).

The Universal Synchronization Switch or IKCM ensures the two X-Ray imaging systems fire simultaneously, therefore providing a pair of X-Ray images from two different perspectives taken at the exact same time. There are two versions of the Halifax Imaging Kits:

a) UNIVERSAL SYNCHRONIZATION (NON-GE BASED CONFIGURATION) The Universal Synchronization Switch synchronizes two independent X-ray systems as accurately as possible by using the manual pushbutton interface of each X-ray system. This replaces the synchronization switch that was described in our predicate K121345.

b) IMAGING KIT CONTROL MODULE (GE BASED CONFIGURATION) The general purpose of the IKCM is to coordinate and control the activities of the detector and workstation with the activities of the generator, as well as coordinate the exposures between the client's clinical system and the Halifax Imaging Kit for RSA exposures. The current version of the IKCM is designed specifically for interfacing with the following components:

•GEHC WDR1 Upgrade Kit which consists of a 'Flashpad' detector, a workstation named 'MagicPC', and a 'Cabinet' for power distribution and communication control. Integrating with a pre-existing system (GEHC Discovery XR656 Plus).

· EMD Technologies Epsilon Series generator. (Or generators already on site)

AI/ML Overview

The provided text describes a 510(k) premarket notification for the "Halifax Imaging Kit," a stationary digital x-ray system. The submission focuses on demonstrating substantial equivalence to a predicate device (Halifax SR Suite 1.0, K121345).

Based on the information provided in the document, here's a breakdown of the acceptance criteria and the study that proves the device meets them:

No specific acceptance criteria table or quantitative performance metrics are explicitly stated in this 510(k) summary. The submission focuses on demonstrating "substantial equivalence" rather than proving specific performance metrics of the device itself. The primary "study" to meet acceptance criteria relies on demonstrating that the new device configuration (Halifax Imaging Kit) is as safe and effective as its predicate device and that its components (like digital panels) already have their own 510(k) clearances.

Therefore, the "acceptance criteria" here is primarily about fulfilling the FDA's requirements for substantial equivalence, rather than meeting specific quantifiable performance targets for a diagnostic or AI-driven system.

However, I can extract information related to the closest aspects of your request:


1. Table of Acceptance Criteria and Reported Device Performance

As noted, there is no explicit table of acceptance criteria with quantitative performance metrics for this device as it's not a diagnostic AI system. The acceptance criteria for a 510(k) submission of this nature are generally qualitative and relate to safety, effectiveness, and substantial equivalence to a predicate device.

Acceptance Criteria (Inferred from 510(k) process)Reported Device Performance (Summary of how criteria are met)
Equivalence in Intended Use"This is a stationary digital x-ray system for general radiography and RSA (Roentgen Stereophotogrammetric Analysis procedures). Not for mammography." - Unchanged from predicate.
Equivalence in Technological Characteristics (Components)New kit integrates FDA cleared/certified X-Ray components. Compared in a "Substantial Equivalence Chart" (Page 5-6) showing similar or equivalent components (Generator, Maximum output, Stand, Image Acquisition, Digital Panel, Digital Resolution, Software, Acquisition Software, Collimator, Safety).
Equivalence in Safety"The results of bench and standards testing indicates that the new device is as safe and effective as the predicate device. Risk analysis has been performed." "UL listed and EMC tested power supply used in the Imaging Kit."
Equivalence in Effectiveness"The results of bench and standards testing indicates that the new device is as safe and effective as the predicate device." "Every installation undergoes a precision validation test... a phantom study was undertaken using a small carbon fibre box. Phantom studies, commonly used for RSA validation, are a technique used to calculate in vitro precision and accuracy of an RSA System."
No New Indications for Use"has no new indications for use"

2. Sample Size Used for the Test Set and Data Provenance

  • Test Set Description: The "test set" primarily refers to components, bench tests, and a phantom study.
  • Sample Size: Not applicable in the traditional sense of a clinical or image-based test set for an AI/diagnostic algorithm.
    • For the bench testing, no "sample size" of patients or images is mentioned. It refers to testing of the Universal Synchronization Switch (board level functionality, firmware, enclosure wiring) and the Imaging Kit Control Module.
    • For the phantom study (for precision validation per installation), the sample size would be the "small carbon fibre box" used for in vitro precision and accuracy calculation. No specific number of phantom images or measurements is given, but it implies a single phantom setup used for validation.
  • Data Provenance: Not explicitly stated for specific data points other than the general context of the company being Halifax Biomedical Inc. (Canada) and the submission to FDA (USA). The phantom study refers to validation at a "[Hospital]" in "[City]" ([Room details]), "[State/Province]", "[Country]" – implying it could be anywhere, but the company is Canadian. The data is prospective in the sense that the bench testing and phantom validation are performed as part of the device development and installation process.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

  • Not applicable. This submission does not involve human expert adjudication of medical images to establish ground truth for a diagnostic algorithm. The "ground truth" for the device's functionality relates to its mechanical/electrical performance, precise synchronization, and ability to perform RSA measurements.
  • The "experts" would be the engineers and QA personnel performing the bench tests and the precision validation (phantom study). Their qualifications are typically implied by their roles in medical device development and testing.

4. Adjudication Method for the Test Set

  • Not applicable. No human image-reading adjudication method is mentioned as this is not a diagnostic imaging AI system. The "adjudication" of performance is done through objective bench test results and phantom study measurements against expected performance, rather than through consensus of human readers interpreting clinical images.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

  • No. An MRMC study was not done. This device is an X-ray system, not an AI or CAD system intended to assist human readers. The document explicitly states "Clinical testing was not required to establish equivalence because all of the new digital receptor panels already have their own 510(k) clearances."

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done

  • Not applicable. This is an X-ray imaging system, not a standalone algorithm. While it produces images for Roentgen Stereophotogrammetric Analysis (RSA), the "algorithm" for RSA (RSA-CMS software) is stated to be "Unchanged" from the predicate device and was cleared under K042383. The submission is about the kit that acquires the images, not a new RSA analysis algorithm.

7. The Type of Ground Truth Used

  • Engineering specifications and physical measurements (for bench testing and phantom studies).
    • For the Universal Synchronization Switch and Imaging Kit Control Module: Proper Board level functionality, firmware performance, proper enclosure internal wiring assemblies and connections.
    • For the RSA System precision: In vitro precision and accuracy calculated using a phantom study (small carbon fibre box) consistent with common RSA validation techniques. This relies on the known physical properties and movements of the phantom as the "ground truth."
    • For the digital receptor panels: Their own prior 510(k) clearances serve as evidence of their established performance and safety, essentially acting as their "ground truth" for those components.

8. The Sample Size for the Training Set

  • Not applicable. This device is an X-ray imaging system, not an AI or machine learning algorithm that requires a training set. The software for RSA analysis (RSA-CMS) is unchanged from the predicate and would have had its own development and validation process earlier, but details are not in this document.

9. How the Ground Truth for the Training Set Was Established

  • Not applicable. See point 8.

8. Summary of Bench Testing and development activities conducted:

The following Risk Management and Risk Analysis documents were created:

Risk Management Plan - Halifax Imaging Kit Risk Management Plan - Imaging Kit Control Module Risk Analysis - Imaging Kit Control Module Risk Analysis - Halifax Imaging Kit - L-Arm Support Fault-Tree Analysis - Imaging Kit Control Module

Design Verification Testing of the Universal Synchronization Switch was performed in order to verify (a) Proper Board level functionality, firmware and (b) Proper Enclosure internal wiring assemblies and connections. Finite element analysis was performed on the support structures followed by design verification reviews.

Verification and Validation reports were executed for the new Imaging Kit, Control Module, and Universal Synchronization Switch.

Labeling: Installation and User Manuals were developed for the modified portions of the system, and the original labeling was updated according to the FDA Guidance on Cybersecurity: Content of Premarket Submissions for Management of Cybersecurity in Medical Devices, Guidance for Industry and Food and Drug Administration Staff Document Issued on: October 2, 2014.

The following reports were prepared documenting bench testing activities:

Design Verification Test, Universal Synchronization Switch

Imaging Kit Control Module Verification Report

Imaging Kit Control Module Validation Test Report

In addition a Requirements Traceability analysis was performed for the Imaging Kit Control Module. The power supply chosen for the Imaging Kit Control Module is UL listed and EMC compliant for medical applications per IEC Standards: IEC 60601-1 and IEC 60601-1-2.

Every installation undergoes a precision validation test prior to turn over to the customer. "The precision of a Radiostereometric Analysis (RSA) System is affected by the components of the RSA System set-up as well as by the features of the individual joint and implant under examination. To validate a new Halifax Imaging Kit at "[Hospital]" in [City] ([Room details]), [State/Province], [Country], a phantom study was undertaken using a small carbon fibre box. Phantom studies, commonly used for RSA validation [1-12], are a technique used to calculate in vitro precision and accuracy of an RSA System."

    1. Summary of Clinical Testing: Clinical testing was not required to establish equivalence because all of the new digital receptor panels already have their own 510(k) clearances.
    1. Conclusion: After analyzing bench testing, standards testing data, and risk analysis it is the conclusion of Halifax Biomedical that the Halifax Imaging Kit Option is as safe and effective as the predicate device, has no significant technological differences, and has no new indications for use, thus rendering it substantially equivalent to the predicate device.
